What type of information is found in blocks 1 through 13 of the CMS-1500?

Blocks 1 through 13 of the CMS-1500 form primarily contain patient and insurance coverage information, which is essential for processing a claim. This section captures key details such as the patient's name, date of birth, address, and insurance policy number. These blocks set the foundation for the claim by ensuring that the healthcare provider has the correct information about who is receiving the services and which insurance plan will be billed for those services.

This information is vital for verifying eligibility and determining benefits. It helps streamline the billing process, ensuring that different parties involved have access to the necessary data to facilitate payment for the services rendered. By accurately filling out these blocks, providers can avoid delays in payment due to missing or incorrect patient and insurance information.
